95 GTX loud bang, dead on water

[Tylertowles]

Bought a 95 GTX in '14. Ran great all that summer. The next summer (2015) I pulled it to the lake for the first time. Cranked right up, took off down the lake. Almost full speed and POP! I floated to a stop. Tried to start it up again and it would not crank. Sounds like the battery is almost dead but I had put a brand new battery in that morning. Would not turn over completely.

Now due to busy schedule I did not get around to looking at it or getting it to a shop so it sat up until now. Just for general maintaince, yesterday I replaced the spark plugs, charged the battery, checked the fuses and starting solenoid.

Has anyone experienced the loud pop that completely kills the machine? I am new to jet skis and any advice would be a great help.

Only loud pop would be a coupler coming off/apart..but, that would then have water in the hull...

That wouldn't explain why it would shut off and not crank again though would it? I will check them though. I do not recall taking on much water.

Could it be the starter Bendix jammed?

 

[Tylertowles]

Well it is trying to turn over it is just very weak. I am not getting any fire from the spark plugs. Could it be the starting coil? How would I go about testing that?

 

[Rabid]

Any fuses blown?

 

[Tylertowles]

No fuses blown but I have only looked at two in the gray box. Are there any more that I need to be looking for?

 

[Rabid]

There may be one off the solenoid

You could have lost the trigger or timing. If the timing got off that would cause a backfire. To be sure... my ski back fired while I was working on it.... rocked the neighborhood. I thought something blew up. Check your Trigger and magneto to see if they are still working (ohm meter)

So I pulled the starter and the bendix did have some extensive damage. I ordered one. I am afraid the fly wheel might be damaged pretty extensively also. I'm going to put the new starter in and go from there.

 

[etemplet]

I wonder if your stater stayed engaged when you started the ski. Then when you reached top speed it couldn't take any more and let go.

 

[Tylertowles]

I believe that may be the case. It would explain the pop I heard.

 

[Rabid]

If you pull the plugs can you spin it by hand or does it bind?

 

[Tylertowles]

I could spin it by hand, however there was some metal on metal rubbing, which led me to pull the starter out.

 

[Rabid]

Etemplate stated that the trigger might have been damaged. Like you stated the flywheel might have turned into shrapnel in the housing. What do you guys think? I would pull the cover and check it.

Don't buy an aftermarket starter. They are junk.

Update: I have changed the starter and bought a new battery. It is now attempting to turn over but it's still very weak and will only do it maybe twice before I put the battery back on charge.
